Security window or door in a burglar-retardant embodiment

A security window (1) or door in a burglar-retardant embodiment, having a frame (2), which is permanently connectable to a building part (G), and a casement (3), which is mounted so it may be turned and tilted therein and is provided with a filling (4), and which is connected to the frame (2) in its closed position (5) via locks (6) and, in its tilted position (7), at least in the area of the casement leg (F4) assigned to the tilt axis, is also connected to the frame (2) via locks (6) and in the area of the diametrically opposite casement leg (F1) via at least one scissor hinge (8), the locks (6) being situated in diametrically opposing pairs on the casement (3) and the frame (2) and being able to be engaged and disengaged using a connecting rod (11), which is mounted in the casement (3) and is displaceable parallel to the plane of the filling (4), in the closed position (5) of the casement (3), one end of the scissor hinge (8) being removable by displacing the connecting rod (11) from the bearing element (9, 9′, 9′″) on the casement (3) or on the frame (2), so that the casement (3) is turnable out of its closed position (5) around a turn axis perpendicular to the tilt axis into an open position (12), furthermore, sections (13.1 through 13.4) of the connecting rod (11), which are situated on neighboring casement legs (F1 through F4), being frictionally coupled to one another via corner deflectors (14), wherein at least one connecting rod block (15, 15′, 15″) on at least one casement leg (F1 through F4) prevents a displacement of the assigned section (13.1 through 13.4) of the connecting rod (11) when the casement (3) is in the tilted position (7), or only allows a displacement path which is required in the closed position (5) of the casement (3) to disengage the scissor hinge (8) and a bearing element (9, 9′, 9′″) on the casement (3) or the frame (2).
